Configuration of the easy-NET
network

easy-NET is configured so that every station can send its
messages. This means that the station must observe a pause
time between sending messages. The pause time increases
the higher the number of stations and the lower baud rate
setting.
The number of stations is recognised by every station via a
“sign of life” signal.
Signs of life of the individual stations and diagnostics
The inputs and outputs message type is used as a “sign of
life” recognition to ensure that the state of the station can
be recognised by other stations. The states of the inputs and
outputs are sent cyclically and at the set baud rate,
irrespective of the SEND IO setting. If the inputs and outputs
of a station are not recognised by other stations after a time
determined by the baud rate, the station is deemed to be
disconnected until the next “sign of life” is recognised.

The following applies to fast message transfer:
• Set the fastest possible baud rate to suit the network
length and cable cross-section.
• Fewer messages means faster messages.
• Avoid program downloads during the RUN mode.
